New U. of Colorado at Boulder flu chip may help combat future epidemics, pandemics

...Kuchta. While the avian virus does not now spread effectively from person to person, world health officials are fearful the strain will mutate and become transmittable between humans, possibly triggering a worldwide pandemic. "If an unusual flu subtype surfaces that has characteristics of both avian and human ...

... the plans for information release. Although it is effectively 18 years from now, current donors ought to have at least some idea of how that is to be managed." She added that it was also important to make clear the level of commitment required as this had possibly contributed to the 30% drop-out rate over the ...

Engineered Stem Cells Show Promise For Sneaking Drugs Into The Brain

Polio vaccination strategies assessed as eradication nears

...easons for stopping vaccination once poliovirus is effectively non-existent, and the risks associated with doing so. Whereas Hull and Minor blame politics and complacency as ultimately being the biggest threats to polio eradication, they conclude that choosing an appropriate vaccination strategy to prevent poli...

Compound from marine bacteria shows potential as multiple myeloma therapy

... They found that the cancer cells were killed more effectively by the combination than either compound alone ?without additional toxicity to normal cells. "This is a laboratory advance that shows clinical promise," says Dr. Chauhan. "We think this is going to be the '2006 Model' of proteasome inhibitors." Mich...

Jefferson researchers find nanoparticle shows promise in reducing radiation side effects

...ls, it blocked the formation of new blood vessels, effectively cutting off the supply of nutrients to the malignant cells. This effect was seen in both the test tube and animal experiments. This type of gene therapy "may be a potent strategy to treat many malignant tumours, including pancreatic cancer, and repr...

Breaking the mold: Research teams sequence three fungus genomes

...ce is going to be central for developing tools for effectively managing A. fumigatus infections as they become more prevalent in the aging population," predicts first author William Nierman, a microbiologist at TIGR. Nierman co-authored two additional Aspergillus genome papers in the same issue of Nature. O...

Membrane research opens window to benefits for plants, humans

...n closed, its pore size is reduced by 2 angstroms, effectively closing the channel, the Swedish researchers reported. The work taken together, Tajkhorshid said, is a landmark study in membrane channels. It addresses the mechanism of gating and regulation of plasma membrane proteins in full detail. "We could see...

Nanoparticles, nanoshells, nanotubes: How tiny specks may provide powerful tools against cancer

..., suggesting that the antibody-nanoshell treatment effectively destroyed HER2 over-expressing cancer cells. The research team is now planning to test this strategy in animal models. According to Gobin, Lowery, and the Rice University faculty they work with, nanotechnology to treat cancer takes advantage of muc...

NIAID researchers show how promising TB drug works

...s Dr. Barry. Using the NimbleGen technique, which effectively re-sequences the entire genome of the bacterium, the scientists quickly pinpointed the protein altered in the PA-824-resistant mutant strains of M. tb. In the past, such a complete genome comparison might have taken many months of work; this new tech...

University of Delaware researchers develop cancer 'nanobomb'

...re exploded and kill cancer cells, macrophages can effectively clear the cell debris and the exploded nanotube along with it. Other treatments retain the carbon nanotubes and nanoparticles intact. If the material finds its way to the kidney or accumulates in the blood vessels, the nanoparticles might cause bl...

Biotechnology's newest chemical tool

...ases within a DNA sequence, methyltransferases can effectively shut a gene off. Methylation plays an important role in embryonic development, genomic imprinting, and carcinogenesis because it regulates gene expression. Methyltransferases require a source for the methyl groups that they attach to DNA, and most ...

In two separate experiments conducted in SFBR's biosafety level 4, maximum containment laboratory, researchers placed anthrax spores in the nasal passages of guinea pigs, mimicking exposure to inh...

Picky female frogs drive evolution of new species in less than 8,000 years

...istinctively different call, and because they were effectively isolated from surrounding populations by mating preference, Hoskin and colleagues concluded that female choice led to this new species. Interestingly, evolutionary theory would predict that the southern and northern frog populations would drift apar...
